反序列化List

反序列化List

(1)使用jackson-mapper

@Test
    public void test_2(){

    	
    	String json="[{\"name\":\"whuang\"},{\"age\":\"abc\"}]";
    	ObjectMapper mapper = new ObjectMapper();
		try {
			List list= mapper.readValue(json, List.class);
			System.out.println(list.size());
			System.out.println(list.get(0) instanceof Map);
		} catch (Exception e) {
			e.printStackTrace();
		}

    }

 pom.xml:

<!-- Json转化模块 -->
		<dependency>
			<groupId>org.codehaus.jackson</groupId>
			<artifactId>jackson-mapper-lgpl</artifactId>
			<version>1.9.9</version>
		</dependency>

(2)使用json-lib

//反序列化
    @Test
    public void test_3(){
    	String json="[{\"name\":\"whuang\"},{\"age\":\"abc\"}]";
    	JSONArray js = JSONArray.fromObject(json);
		List jRpcReq = (List) JSONArray.toCollection(js,Map.class);
		System.out.println(jRpcReq.size());
		System.out.println(jRpcReq.get(0) instanceof Map);

    }

pom.xml:

	<dependency>
  		<groupId>net.sf.json-lib</groupId>
  		<artifactId>json-lib</artifactId>
  		<version>2.4</version>
  		<classifier>jdk15</classifier>
  	</dependency>
